I've used CentOS 7 as a host for KVM guests for several years now. I'm using the CentOS Virtualization SIG's version of qemu specifically because I was anxious/curious to try making VMs with UEFI (OVMF). I also transitioned to using Virtio-SCSI a few years ago, so when I started experimenting with OVMF, I used Virtio-SCSI for the block devices, as usual. In that environment (more details below), everything Just Worked.
I'm now experimenting with using Fedora 30 to host guests using KVM. I have successfully create a guest using Q35/OVMF. I used a VirtIO-SCSI block device, as I've done on CentOS in the past. The guest (Fedora 30 Server) PXE network booted in UEFI mode, and correctly installed F30 Server to the block device, creating a UEFI System Partition and a GPT disk. However, it wouldn't boot. I poked around, comparing the guest made on the F30 host to the guest made on the C7 host, pressing "F2" when the guest booted to get into OVMF's UI. It was there that I realized that OVMF didn't "see" the VirtIO-SCSI block device at all. It didn't list the entire drive it as a boot option, and it (obviously) didn't show the UEFI boot entry stored on its UEFI System Partition. I switched the device to a VirtIO device, and it booted right up. So, now I'm wondering if I've missed something. Should OVMF be able to recognize a VirtIO-SCSI block device on a Fedora 30 KVM host? Did something change between what I've been using on CentOS 7 and here to remove that? Or was I maybe just getting lucky on C7 all along, successfully doing something that shouldn't be working? Below are some of the packages I have installed on my two VM hosts. The Fedora 30 host is very standard. The C7 host has packages from C7's virt SIG, so they're newer than the KVM offered in C7's base install. The base packages don't support Q35/OVMF at all. (Always made me wonder why RHEL 7 included OVMF, but no way to use it.) I noticed that the guest created on CentOS is using this as the UEFI: /usr/share/OVMF/OVMF_CODE.secboot.fd but the one created on F30 used /usr/share/OVMF/OVMF_CODE.fd instead. I edited the VM to use OVMF_CODE.secboot.fd on the F30's VM, but it still didn't work (the disk was still not recognized when I used F2 to enter OVMF's interface).
